To attach the upper
bellows, move the shaft to its lower limit.
To attach the lower bellows, move the shaft to its upper limit.
To move the shaft up/down, press and hold the brake release switch.
Be sure to keep enough space and prevent t
he end effector
hitting any peripheral
equipment.
The brake release switch is applied to both Joints #3 and #4. When the brake
release switch is pressed, the respective brakes of the Joints #3 and #4 are released
simultaneously.
(The brake for Joint #4 is only installed to G6-**3**.)
Be careful of the
shaft falling and rotating while the brake release switch is being
pressed
because the shaft may be lowered by the weight of an end effector.
(2)
Pass the shaft through the bellows
from the larger joint.

Secure the cover side of the bellows.
The bellows has two joints:
The larger joint must be attached to the cover side.
The smaller joint must be attached to the end face
side of the shaft.
Be careful not to misplace the clamp bands. The
clamp band has
three sizes; small, medium, and
large.

until the
end touches the
cylindrical part of the cover.
